humidity.

Simplistic reasoning of a mere human is no substitute for detailed
climatological models. Leave the extrapolation to the professionals.

True, but this was the reasoning of professionals some forty or more years
ago and made them worry that clearing the Arctic Ocean of ice would trigger
a new ice age. It was one of the reasons why the USA decided not to
progress with experiments for clearing the ice. I agree that, at the
moment, computer models do not agree that this scenario is possible.

The summertime Arctic ice cover has broken up for the first time in
recorded history; and is no, for the first time, no longer traversible.

Both statements in this sentence, as I understand it, are untrue. It can be
corrected by removing both instances of the phrase "for the first time".

A new Northwest passage has started opening up.

So? A new NW passage as opposed to the old one? Even if you mean the NW
Passage is almost open this Summer - so what? I can remember the odd
occasion in the sixties when it opened up. I can also remember the NE
passage opening during that period. What is now different is that they are
both close to being open during the same year. In the past, if the USSR
coastline was ice-free, that of Canada and Alaska would have the pack-ice
close onshore, and vice versa.
